Simulate Text Degradation
The Remove Random Letters Tool simulates what happens to text when data degrades over time, when transmission fails, or when someone types sloppily. By randomly deleting characters, you can test how robust your systems are against imperfect input.
How to Use
- Set intensity - Low (5-15%) for realistic typos, high (50%+) for severe decay
- Toggle preserve - Keep first/last chars to maintain readability
- Enter text - Paste or upload your content
- Review degradation - See statistics on letters removed
- Download - Save decayed text as TXT
Common Use Cases
Autocorrect Testing
Test if spell-checkers and autocorrect systems can handle missing letters and identify intended words.
Data Corruption Simulation
Simulate transmission errors, file corruption, or degraded storage to test recovery systems.
Robustness Testing
Test search engines, NLP systems, and parsers with degraded input data.

Frequently Asked Questions
What is this tool used for?
This tool simulates data degradation, sloppy typing, transmission errors, or corrupted text files. It's useful for testing autocorrect systems, spell-checkers, reading comprehension under noise, and simulating real-world data conditions.
How does the intensity slider work?
The intensity (1-100%) represents the probability of deleting each character. At 10%, roughly 1 in 10 letters is removed (subtle typos). At 50%, half the letters are deleted (heavy degradation). At 100%, nearly all letters are removed.
What does 'Preserve First/Last Char' do?
This setting protects the first and last letter of each word from deletion, only removing middle letters. Studies show humans can still read words when the outer letters remain intact, even with scrambled or missing middle letters.
Can words become completely blank?
At very high intensity (80-100%) without preserve mode, yes, shorter words can be deleted entirely. With 'Preserve First/Last Char' enabled, words will always retain at least 2 characters, maintaining minimal recognizability.
How does this help test autocorrect?
By creating realistic typos (missing letters), you can test if your autocorrect or spell-checker can correctly identify the intended word. Perfect for QA testing keyboard apps, search engines with typo tolerance, or text input systems.
Can I upload files to process?
Yes! Click the Upload button to load .txt files. Great for batch testing documents, simulating corrupted file recovery scenarios, or creating degraded versions of text for research purposes.
What's a realistic intensity for typos?
For simulating human typing errors, use 5-15% intensity. This creates occasional missing letters similar to real typos. For data corruption simulation, use 20-40%. For severe degradation testing, use 50%+.
How is this different from the Add Letters tool?
The Add Letters tool inserts extra characters (creating glitch effects), while Remove Letters deletes existing characters (creating decay/degradation). One creates noise through addition, the other through subtraction. Useful for different testing scenarios.
Can I download the degraded text?
Absolutely! Click the TXT button to download your decayed text as a plain text file. The filename includes a timestamp for easy organization of test data.
Is my text data private?
100% yes. All processing happens locally in your browser using JavaScript. Your text never leaves your device, and nothing is sent to our servers. Completely private and secure.
